Sleep Mode

I have one of those Microsoft internet keyboards, and it
used to put my computer into sleep mode from the keyboard,
but now it doesn’t. I can’t manually (start->shutdown-

accidentally disabled? Is there a way for me to get this
working again?

Standby, in any machine, can be problematic. Too many things, hardware and
software, must perform to specs for it to work at all. My stock advice is–if it
works, great. If not, forget about it. Not worth bustin’ your b*** over it, and
you will very likely never get it to work again–short of a complete reformat
and reinstall–and even *then*, odds are only even.

If you are dead certain that *nothing* changed on your machine–no new software,
no new drivers, no hew hardware, no new settings–*nothing* has changed, then
it’s likely some hardware component simply reached a certain age and no longer
performs to the same precise specs as it did before.

However, I’m not certain this advice applies to the OP’s problem–different
issue, I *think*.

When you say, “I can’t manually (start->shutdown->standby) either.”, that’s a
strong hint that it probably has nothing to do with the keyboard. Still, you
might want to start trouble-shooting by uninstalling and reinstalling the
keyboard’s software support, maybe uninstalling and reinstalling the keyboard in
Safe Mode Device Manager, too. But…

Only thing I would even bother trying is to first disable Power Management
completely in BIOS, then reboot into Safe Mode and remove all devices directly
relating to it (anything that mentions Power Management, ACPI, etc., *and* the
keyboard), reboot to Normal Mode, then restart to BIOS, re-enable Power
Management (but disable any BIOS timers), reboot into Safe Mode, again remove
and related devices, if any exist, then reboot into Normal mode again…

And if it doesn’t work, give up. Standby on a personal PC is highly over-rated,
IMO, anyway. Use monitor, and maybe disk, Suspend timers, and shut down the
machine when you are going to be away for longer than a few hours.
